I have a k12 micra that I had the valve stem seals replaced I also did a new timing chain as well, I removed the whole engine because theirs simply not enough space to work. I intalled everything back in its place I took alot of photos when undoing everything but now it wont start. When I turn the ignition theirs no dash lights. No horn, when you press the hazzard button in the lights only blink ones the back light on the dash works when you turn on the lights but the lights them selfs dont work theirs no brake lights ect. I have checked all the fuses and used a continuaty tester and all works can anybody pls help me???
